As of this posting there are 14 homes for sale with Lake Austin waterfront. The homes range from 1,200 to almost 10,000 sqft. Prices from about $450 to $1,400 per sqft. I am ignoring the almost $4,000 per sqft teardown, but it makes a nice shock-value. Prices from $775K to 13.5M.

Location is important - relative to town and part of the lake. Linear feet of waterfront is also a big factor. As is the build quality of the home. And of course how it all comes together.
